DISCUSSION
ISSUED AT 1132 AM MDT WED SEP 9 2026
WARM AND DRY CONDITIONS:
HIGH PRESSURE THAT HAS BEEN CENTERED OVER THE CENTRAL US IS GETTING
NUDGED BACK WEST BY SHORTWAVE ACTIVITY ACROSS THE NORTHERN TIER.
THIS WILL RESULT IN DRY WESTERLY FLOW FOR THE NEXT FEW DAYS. IT
WILL ALSO CAUSE TEMPERATURES TO RANGE FROM 5-10 DEGREES ABOVE
NORMAL.
SOME DEEPER MIXING WILL BRING SOME GUSTY WINDS TO THE SURFACE TODAY
AND TOMORROW WHILE HUMIDITIES HOVER AROUND 10 TO 15%. HOWEVER, THE
GUSTY WINDS WILL BE MARGINAL AT BEST. SO DESPITE THESE VALUES BEING
CLOSE TO CRITICAL FIRE WEATHER THRESHOLDS, ONLY LOCALIZED CRITICAL
FIRE WEATHER CONDITIONS ARE EXPECTED MAINLY FOR THE FOUR CORNERS
REGION.
POTENTIAL MOISTURE INCREASE:
AS FAR AS OUR NEXT MOISTURE PUSH, MODELS CONTINUE TO HIGHLIGHT PWATS
REACHING UPWARDS OF 150% OF NORMAL FOR THE FRIDAY AFTERNOON ONWARDS.
THIS REMAINS DEPENDENT ON THE EVOLUTION AND TRACK OF AN AREA OF LOW
PRESSURE/TROUGH IN THE PACNW AND THE RESULTANT MOISTURE ADVECTION
THANKS TO A MORE SOUTHERLY WIND FLOW. AS OF NOW THERE IS FAIR MODEL
AGREEMENT THAT THIS SYSTEM STAYS TO OUR NORTH, BUT IT MAY DRIVE A
FRONT INTO THE REGION. ATTM THAT FRONT SEEMS WEAK AND DIFFUSE BY THE
TIME IT REACHES US. IF IT MANAGES TO INTERACT WITH THE MOISTURE IN
PLACE, WE COULD SEE SOME SHOWERS AND STORMS. TIME WILL TELL,
HOWEVER, SO KEEP AN EYE ON THE LATEST FORECAST IF YOU HAVE ANY BIG
WEEKEND PLANS.
